Prima speakers

This little box is just the thing if you want to just listen once in office, holiday or other occasions some music. The sound is surprisingly good for the size - varies, however, with the selection of the selected floor space - preferably a not too thick, empty cupboard or table surface.
Unfortunately, I have a model with no SD slot caught because I was not paying attention when ordering - but then that's my own fault. But I have already bought the device primarily for use with mobile phone via Bluetooth.
The speakerphone and the built-in micro I have not tried yet.
